The care for patients receiving total hip and knee arthroplasty at the University of Arkansas for Medical Sciences has followed a structured care pathway since July 2015. This system of perioperative care has focused on preoperative assessment of medical co-morbidities and risks to postoperative functional recovery, anesthetic care focused on postoperative nausea and vomiting prevention and optimizing immediate postoperative functional ability, and aggressive postoperative physical therapy. This is an observational study to look at the outcomes of this program at University of Arkansas for Medical Sciences. Areas of focus will be hospital length of stay, postoperative narcotic consumption, Visual Analog Scale scores, incidence of postoperative nausea and vomiting, and 30-day readmission rates, and health literacy rates.
The purpose of this study is to compare the outcomes and accuracy of implant positioning in robotic assisted total knee arthroplasty with traditional manually instrumented total knee arthroplasty.
To investigate pain and inflammatory parameters (cytokines, immune cells) in knee joint tissue of chronic arthritis patients following intraarticular (i.a.) injections of morphine, a standard steroid or placebo. The primary hypothesis is that i.a. morphine results in significantly lower pain scores and supplemental analgesic consumption than placebo during the first week after injection, an efficacy comparable to standard i.a. steroid (triamcinolone) medication.
Modern knee implants combine several types of metal and therefore potentially expose patients to different metal ions. Titanium niobium nitride coating (TiNbN) acts like a physical barrier against the corrosion process and the metallic ions release towards the surrounding biologic environment, thus, making TiNbN-coated prostheses possible to be safety implanted in metal sensitized patients. The aim of the study is to verify that the postoperative plasma metal concentrations at 1 year are not different than preoperative values.
Patient-specific instrumentation guides have previously been used to improving surgical accuracy and ease of implantation during Total Knee Replacement but have received less attention for implanting Unicompartmental Knee Replacement. The aim of this prospective study is to compare the accuracy of implantation and functional outcome of mobile bearing medial Unicompartmental Knee Replacement implanted with and without patient specific instrumentation by experienced knee surgeons.
To investigate the association between grip strength and preoperative pain threshold as measured by pressure algometer and validated pain outcome surveys.
The aim of the study is to compare the time of home discharge in day-case patients receiving either a spinal anesthesia or a combined sciatic-femoral nerve block for knee arthroscopy
The purpose of this study is to determine the relative effectiveness of two drug agents, Tranexamic acid (TXA) and aminocaproic acid (Amicar), that act through a similar mechanism of action. These agents are used to decrease blood loss that is a result of major surgery, like total joint arthroplasty. A secondary goal will be investigate the cost-analysis of total hospitalization. Both TXA and Amicar are both currently used in the care of patients undergoing total joint arthroplasty. Subjects will be randomly assigned to the TXA or Amicar arm. All data needed for this study including blood loss, need for transfusion, preoperative and lowest postoperative hematocrit and hemoglobin, and complications will be collected during the hospitalization stay. Our Hypothesis is that TXA and Amicar will have similar effectiveness in preventing intraoperative blood loss and the need for transfusion post-op than Amicar. A detailed cost analysis will show that the overall cost of performing the operative procedure, including transfusions, OR time, and total costs associated with admission cost will be more decreased with Amicar as compared to TXA.
Confinement to bed, which occurs in many pathological situations, induces a muscle atrophy and a loss of muscle strength. Muscle atrophy is associated to impaired performance in motor tasks, such as posture and locomotion, and is therefore a major cause of loss of autonomy. It requires a stay in follow-up and rehabilitation service, and thus lengthens the duration of hospitalisation. Data underline the importance of afferent input integrity in the maintenance of muscle characteristics and postural control, and suggest that countermeasure programs based on the stimulation of proprioceptive inputs could be efficient to prevent muscle atrophy and falls. In particular, fundamental studies performed in rodents by the investigators laboratory have demonstrated that the adverse structural and functional adaptations which occur during muscle deconditioning can be counteracted through adequate physiological stimuli such as activation of proprioceptors. Based on this scientific expertise, the investigators aim is thus to prevent muscle atrophy and its functional consequences on posture and locomotion, following a surgical intervention in humans . The investigators will develop a device allowing stimulation of foot and ankle proprioceptors. In order to facilitate the evaluation of its efficiency, the device will be tested on a selected population confined to bed during a post-operative period (knee replacement). It efficiency will be evaluated by means of three parameters: muscle force of ankle plantar flexor, muscle volume of lower limb muscles, functional outcome (gait and balance analysis). The technique developed in the present project could bring benefits to patients confined to bed, or in elderly. Preventing or retarding development of muscle atrophy will beneficiate to health and quality of life of these patients. In addition, this device might allow to consider therapeutic strategies for prevention of atrophy in neuromuscular pathologies.
